My invention relates to Vises such as are adapted to be used on heavy duty milling machines for holding work thereon to be milled. It is adapted for extreme applications and is adapted to last indefinitely since the body is made of heavy semi-steel casting reinforced with hardened and ground wearing and guide plates.

The object of the invention is to provide a more substantial, durable and practical form of vise for attachment to machine tools than is now to be found on the market and one which is adapted to be attached upon a planer bed or a milling machine bed for securely holding a large variety of work pieces in position to be operated upon, to provide a vise whose body, front and rear jaws, nut and block are made from semi-steel castings, to provide a body that is reinforced on top side with indestructible hardened and ground wearing and jaw guide plates and further to provide jaw guide plates that are serrated to receive serrated blocks on rear jaw and nuts to prevent slipping.

The front and rear jaws and nut blocks are adjustable to provide extra large openings between jaws. A further feature is to provide for the removable attachment of a separate intermediate jaw, to provide two holding positions at one time.

These and other features of the invention are included in the accompanying illustrations of my improved vise as shown on the accompanying two sheets of drawing forming a part of this specification and upon which similar characters of reference denote corresponding parts throughout the several figures.

Fig. 1 shows a perspective view of my improved vise in an open position but not including the intermediate insertable floating jaw.

Fig. 2 shows a top plan View of the vise shown in Fig. 1 and including the intermediate, removable floating jaw not shown in Fig. 1.

Fig. 3 shows a vertical, longitudinal, sectional view through the length of the vise shown in Fig. 2 and taken on line 3-3 of that figure.

Fig.4 is a perspective view of the left hand end portion of the vise as shown in Fig. 1 but including the central floating jaw and also shows an attachable jig fixture as used in drilling oper- I My vise briefly comprises an elongated base having a pair of longitudinal T-slots extending through the upper portion thereof for the attachment and guidance of fixed and movable jaws. Upon this base is mounted four attachable parts comprising a supporting member for aclamping screw, a front movable clamping jaw operated by the screw, a rear jaw that is fixedly attached to the end portion of the vise opposite to that of the clamping jaw and a separate intermediate attachable center floating jaw which may or may not be used as desired according to the class and amount of work to be clamped, but which when used provides two separate jaw openings forming two holding positions to accommodate one or more pieces of stock to be milled. v

The vise as shown in Figs. 2 and 3 includes in addition to its base three clamping jaws A, B and C and a fixed yoke D all of which are adjustably mounted on the base.

With further reference to the characters of reference marked upon the drawings, 10 represents the base of the vise which as shown is provided with ears II on opposite ends for its attachment to the bed of a milling machine, drill or other suitable machine tool, not shown. This bed as'will be seen includes two longitudinal slots l2 -i2 that extend through the upper portion of the base from end to end. The top of the base is further provided with hardened wearing and guide plates l3-l3 on opposite sides and a similarly hardened intermediate plate M which are secured to the top central portion of the base by screws 15 as shown.

The under inner edge portions of these plates slightly overhang the upper side edges of the slots I 2 to form of them T-slots to accommodate shoes IB and blocks I1. The exposed under edge portions of the plates are serrated as at l8, see Figs. 3 and 6, for the engagement of the hardened serrated shoes l6 and blocks I? to prevent slipping, positioned in the said T-slots I2--l2. It will also be noted that the remaining undersurface IQ of these plates which fit on the top surface of the base are finished to closely fit the said top surface of the base and to which they are secured by screws l5.

The shoes l6, see Fig. 3, are in the form of nuts and are small enough to be shifted longitudinally in the slots when the clamping screws are loosened whereas the blocks H are not serrated but' have a finished upper surface to engage the undersurface of the central or inter- I mediate jaw C, adapted to be inserted in the T-slots from the end of the bed and adjusted thereon for positioning.

This yoke D is fixedly attached to the bed by means of screws 20 that extend through opposite end portions of the yoke and engage shoes [6 positioned one in each T-slot [2. An adjusting screw 2! is threadably mounted in the yoke and is provided with a collar 22 that is enclosed in a pocket of the clamping jaw B and covered by a steel plate 23 secured thereto by screws 24 and provided with a V-groove 25. This jaw B is slidably mounted on the base guided by the T-slots and provided, as shown in Fig. 3, with a block [1 positioned in the T-slots and attached to the jaw by screws 26 and which is adapted to be moved backward and forward in the slots by the operation of the clamping screw.

The jaw A is mounted on the rear end of the base and secured thereto by clamping screws 21 that extend through opposite side portions of the jaw and into the T-slots and threadably engages the shoes l6 whereby the said end jaw is securely though adjustably attached to the base. This jaw like those previously mentioned has a hardened plate 28 secured to its face by means of screws 29 and is further provided with vertical V-grooves 30 to insure firm engagement of the work piece.

The attachable intermediate jaw C shown in Figs. 2 and 3 is in a sense a floating jaw since it is not firmly secured to-the bed but may be slipped along and positioned where desired as between the end jaw and the clamping jaw. It is provided with hardened steel plates 3i on opposite faces and secured thereto by screws 32. The said jaw is slidably held in position through the blocks [1 which are secured to the jaws by screws 26 and are longitudinally adjustable in the T-slot since it has no serration to engage those of the plates l3-l3 and I4.

Inasmuch as my improved vise has been designed for use upon machine tools, such as milling and drilling machines, it will be understood that its particular application in this respect is for supporting one or more work pieces usually in spaced relation, for milling, drilling or tapping difierent classes of work and in this connection it is also desirable to provide for the use of suitable jigs and fixtures whereby the tools may be accurately set and used to the best advantage. My vise is accordingly well adapted for the use of the above class of fixtures and although the latter necessarily varies somewhat as to design it will be seen from Fig. 4 of the drawings that a simple form of fixture to be used for drilling or tapping can be applied to advantage and as will be noted comprises an L-shaped member 33 whose depending slotted portion 34 is secured to the back jaw A by means of a screw 35. To the top portion of this angle piece is adjustably secured an arm 3% by means of a screw 3i, the forward end of the arm being adapted to hold a guide bushing 38 through which a drill is guided to the work piece, not shown.

In Fig. I have shown a new type of multiple jig bushing plate attachment 3% adapted for gang drilling. As will be seen it carries a series of bushings 38 in spaced relation and the plate 39 as a whole is adapted to be attached to the top of the angle piece by means of several screws 31 positioned one in each slot and engaging tapped holes in the angle piece so that the line of bushings will be disposed crosswise of the vise above the space between the members B and C.
